Description:

BACKGROUND OF THE INVENTION

Skiing and snowboarding are popular sports enjoyed by many people throughout the world. Winter resorts typically have ski-lifts that include ski-lift chairs having a restraint bar across the front to prevent riders from falling out. Winter resorts also often have trail signs and maps posted at locations such as the tops and bottoms of the ski lifts, and at trail intersections; such fixed signage is useful when a viewer is nearby. However, skiers and snowboarders spend a good deal of time riding the ski-lifts, and can use such time reviewing trail maps if they are handy. Riders on ski-lift chairs may also be a somewhat captive audience for advertising materials that may be displayed to the riders.

The present invention relates to a media display system for a ski-lift chair, and more specifically a system that can be mounted to a restraint bar along the front side of the chair.

SUMMARY OF THE INVENTION

In one embodiment, a media display system for a ski-lift chair includes a base member and a plurality of panels. Each panel forms a window for viewing printed media therethrough. The panels are configured to cooperate with each other and with the base member such that securing one of the panels to the base member secures the other panels to the base member.

In one embodiment, a media display system for a ski-lift chair includes a base member having a front edge and a rear edge. The base member forms a flange along the front edge or the rear edge.

DETAILED DESCRIPTION OF THE DRAWINGS

The present disclosure may be understood by reference to the following detailed description of the drawings included herewith. It is noted that, for purposes of illustrative clarity, certain drawings and elements may not be drawn to scale. Numbering without parentheses is used to denote a genus (e.g., media display system 100), whereas numbering with parentheses denotes a species within a genus (e.g., media display system 100(2)). Multiple elements within a figure may not be labeled for the sake of clarity.

FIGS. 1-7 show embodiments of a media display system 20 for a ski-lift chair. System 20 includes body member 22, and has a left side 24, a right side 26, a front side 28 and a rear side 30.

One or more frame members are provided, such as central frame member 50, right frame member 52 and left frame member 54. Preferably, each of these frame members partially or completely encloses a central viewable region, such as viewable region 56 through which printed media 60, 62 and 64 may be seen. Printable media 60, 62 and 64 are illustrated in FIG. 1 and show the words “MAP” and “AD” in dashed lines to represent imagery thereon. In one embodiment, each of the printed media has a top side 66 and an opposite side (hidden in the view of FIG. 1) facing downwardly towards body member 22. Printed media 60, 62 and 64 may be protected by or integrated with a clear plastic film of at least several mills in thickness. Moreover, the imagery may be reverse printed in the bottom side of such film. For example, the bottom side of printed media 60 may first be reverse printed with map indicia, trees, and so forth, and subsequently printed with a backing color (e.g. white ink). In this way, when printed media 60 is mounted between frame member 50 and body member 22, the top surface 66 which typically is exposed through viewable region 56 protects the printed ink from scuffing, wear and the like.

As also illustrated in FIG. 1, one approach is to utilize three frames: left frame member 54, right frame member 52 and central frame member 50. It may be preferable to have a map in central region 50 to show paths and terrain of a ski area in which the ski-left chair is located, with advertisements in frames 52 and 54. Such advertisements may be sold or leased as a revenue source. Naturally, other combinations may be used, including advertisements in the middle and maps on either side, all advertisements, all maps, or other printed media. It is also possible to have a different number of frame members than the three frame members shown in FIG. 1. It is possible to have permanently installed printed media. However, it may be preferred to have interchangeable printed media 60, 62 and 64, held between the frames and the body member so that the printed media may be changed from time to time.

Optionally, printed media 60, 62 and 64 may have holes cut therein such as a hole opening 68 through which a downwardly projecting tab 58 may pass. Preferably, 58 is equipped with a latch tab which snaps into place in a corresponding opening in body member 22 to hold frame 50 in place. As illustrated in FIG. 1, a plurality of tabs 58 with and/or without latch tabs may be provided, with corresponding openings 68 punched or otherwise formed in printed media 60, 62 and 64. Tabs 58 thereby provide registry and maintain printed media 60, 62 and 64 flat and smooth along a top surface 32 of body member 22. Preferably, one or more fasteners such as screws 25 are screwed through holes, such as hole 27 (see FIG. 1) located in a perimeter flange of body member 22. Only a few screws 25 are shown in FIG. 1, for clarity of illustration. Screws 25 are screwed upwardly into the corresponding frame member to help hold it in place. In a preferred embodiment, left and right frame members 52 and 54 are held in place by only two screws 25 and two hooks 29 in opposite inboard ends of frame 52 and 54, two such hooks 29 shown associated with frame 52 in FIG. 1 (other hooks being associated with frame 54 but hidden in the perspective view of FIG. 1).

Optionally, body member 22 includes one or more topside recesses, such as topside recess 34, molded therein to provide dimensional stiffness in body member 22 and to provide a bottom surface on which to mount loop members 36, 37 and 38 (see FIG. 5). Loop members 36, 37 and 38 may be formed from metal strips wrapped in a loop which goes around a restraint of a ski-lift chair. Loop members 36, 37 and 38 preferably have a top flange and bottom flange projecting tangentially from the circle formed by the loop, with the top flange and bottom flange having aligned holes drilled therein. A screw 35 passes through both of the aligned holes and secures the corresponding loop member to a bottom side of one of the topside recesses 34 of body member 22. For example, FIG. 5 shows one such screw 35 holding loop member 36 in place screwed into recess 34 of body member 22. Preferably, body member 22 is molded with twin screw holes corresponding to each topside recess 34, one of the twin holes being disposed on a forward side and the other on a rearward side of each recess 34. In this way, as illustrated in FIG. 5 by the staggering position of loop members 36, 37 and 38, the loop members may be oriented such that the flanges and screws 35 holding each loop member in place are alternately in forward and reverse configurations along a length of body member 22. In this way, the screw holes are in a non-linear arrangement, providing a more stable and secure base for mounting system 20 to the restraint bar of the chair lift. As the screws 35 are tightened down, the flanges are urged together, cinching the loop members tightly around the restraint, gripping it tightly and preventing system 20 from rotating with respect to the restraint.

Preferably, system 20 has an ornamental appearance which is also aerodynamic. In this regard, one aspect of this is that the length “L” (see FIG. 4) is greater than the thickness “T” of system 20, and preferably is at least two times, and preferably three times greater than thickness “T”. Moreover, top surface 32 is preferably convex along the direction of the length from front 28 to rear 30. As illustrated in FIG. 4, semi-cylindrical recess 40 runs along the entire width of system 20 so as to receive the restraint bar therein. Note that as shown in FIG. 4, the metal holding clamps looped around the restraint bar are removed. As illustrated in FIGS. 2 and 5, the front or leading edge 28 faces forwardly with respect to the ski-lift chair and is swept rearwardly along the width of the leading edge from a central region thereof (e.g., approximately the central ⅓ thereof) to the left and the right sides of body member 22. Left side 24 and right side 26 are rounded when viewed from a plan view. The rounding of left sides 24 and 26 facilitates stability of system 20 on a ski-lift chair. That is, rounded sides 24 and 26 present less wind resistance than if sharper corners were present, so that wind forces which might otherwise tend to rotate system 20 about the restraint bar are reduced. Rounded sides 24 and 26 may also facilitate stability of the ski-lift chair itself (as compared to a corresponding system having sharper corners) since such chairs are generally mounted to a cable utilizing pivots, such that high winds cause the chairs to swing.

FIG. 8 shows an exploded view of a media display system 100(1) that is attachable to a restraint bar that lowers in front of a ski-lift chair (not shown). FIG. 8 may not be drawn to scale. Printed media (not shown in FIG. 1) may be displayed by system 100(1), which is configured for keyed access, as explained immediately hereafter. Such printed media may include, for example, trail maps, ski-lift instructions, safety information, and advertising material.

System 100(1) includes a base member 110(1), a center panel 120(1) shown in an open position, and side panels 130(1) and 130(2) shown detached from base member 110(1). Side panels 130(1) and 130(2) form flanges (not shown) configured to slide into grooves 170(1) and 170(2) of base member 110(1). Each of center panel 120(1) and side panels 130(1) and 130(2) include a window 180(1)-180(3), as shown. Each of windows 180(1)-180(3) may include a transparent material such as glass or clear plastic, or windows 180(1)-180(3) may simply be openings in each of center panel 120(1) and side panels 130(1) and 130(2). Center panel 120(1) connects to base member 110(1) by means of hooks or hinges (hidden from view behind base member 110(1) in the viewing angle of FIG. 1) such that panel 120(1) can swing down into a closed position onto base member 110(1).

Installation of printed media into system 100(1) may begin with center panel 120(1) in the open position and side panels 130(1) and 130(2) at least partially removed from base member 110(1). Printed media may be placed on base member 110(1), or affixed to an underside of each of center panel 120(1) and side panels 130(1) and 130(2). Once printed media are in place, flanges of side panels 130(1) and 130(2) slide into grooves 170(1) and 170(2) until each of panels 130(1) and 130(2) abuts one of ends 112(1) and 112(2) of base member 110(1). Next, center panel 120(1) swings into a closed position, such that locking tabs 145(1) and 145(2) of each of two locking devices 140(1) and 140(2) pass through slots 160(1) and 160(2) formed by base member 110(1). When panel 120(1) is in the closed position, ridges along sides 122(1) and 122(2) of center panel 120(1) engage grooves of side panels 130(1) and 130(2), as shown in FIG. 9. In the closed position, a key 150(1) can operate each of locking devices 140(1) and 140(2) so that locking tabs 145(1) and 145(2) engage base member 110(1). Thus, when center panel 120(1) in the closed position holds side panels 130(1) and 130(2) in place, locking tabs 145(1) and 145(2) engage base member 110(1) and key 150(1) is removed, system 100(1) is in a closed and relatively tamper-resistant configuration, with printed media visible through each of windows 180(1)-180(3).

FIG. 9 is a detail view showing how edge 122(1) of center panel 120(1) holds side panel 130(1) in place. FIG. 9 may not be drawn to scale. Center panel 120(1) forms a flange 125(1) at edge 122(1). Flange 125(1) fits within a groove 135(1) formed by side panel 130(1), as shown. Thus, flange 125(1) holds side panel 130(1) in place, in connection with flanges of side panel 130(1) sliding within grooves 170(1) of base member 110(1), as discussed in connection with FIG. 1.

FIG. 10 is a detail view showing a hinge 190(1) that may be utilized in media display systems to connect a center panel to a base member (e.g., may be utilized by system 100(1) to connect center panel 120(1) to base member 110(1). FIG. 10 may not be drawn to scale. Base member 110(1) forms a slot 192. Center panel 120(1) forms an arm 194 that fits within slot 192, and a ball 196 that is larger than slot 192, so that when arm 194 is within slot 192, center panel 120(1) can rotate in directions R−, R+ with respect to base member 110(1) about a hinge axis 198. In normal use, when center panel 120(1) is in the closed position, panel 120(1) is rotated in the R+ direction and is held in place by locking devices 140(1) and/or 140(2) (shown in FIG. 1). FIG. 10 shows hinge 190(1) in the open position, with panel 120(1) rotated far enough in the R-direction that ball 196 and thus panel 120(1) are completely disengaged from base member 110(1). The ability to disengage center panel 120(1) easily form base member 110(1) may be advantageous when cleaning or replacement of center panel 120(1) is desired.

FIG. 11 shows an exploded view of a media display system 100(2) that is attachable to a restraint bar that lowers in front of a ski-lift chair (not shown). FIG. 11 may not be drawn to scale. Like system 100(1) (FIG. 1), system 100(2) may display printed media, and is configured for keyed access, as explained immediately hereafter.

System 100(2) includes a base member 110(2), a center panel 120(2) shown in an open position, and side panels 130(3) and 130(4) shown detached from base member 110(2). Side panels 130(3) and 130(4) form flanges (not shown) configured to slide into grooves 170(3) and 170(4) of base member 110(2). Each of center panel 120(2) and side panels 130(3) and 130(4) include a window 180(4)-180(6), as shown. Each of windows 180(4)-180(6) may include a transparent material such as glass or clear plastic, or windows 180(4)-180(6) may simply be openings in each of center panel 120(2) and side panels 130(3) and 130(4). Center panel 120(2) connects to base member 110(2) by means of hooks 127(1) and 127(2) that engage with holes 114(1) and 114(2) formed by base member 110(2) such that panel 120(2) can swing down into a closed position onto base member 110(2).

Installation of printed media into system 100(2) may begin with center panel 120(1) in the open position and side panels 130(3) and 130(4) at least partially removed from base member 110(2). Printed media may be placed on base member 110(2), or affixed to an underside of each of center panel 120(2) and side panels 130(3) and 130(4). Once printed media are in place, flanges of side panels 130(3) and 130(4) slide into grooves 170(3) and 170(4) until each of panels 130(3) and 130(4) abuts one of ends 112(3) and 112(4) of base member 110(2). Next, center panel 120(2) swings into a closed position, such that a locking tab 145(3) of a locking device 140(3) passes through a slot 160(3) formed by base member 110(2). When panel 120(2) is in the closed position, ridges along sides 122(3) and 122(4) of center panel 120(2) engage grooves of side panels 130(3) and 130(4), in the same manner as shown in FIG. 9 for panels 130(1). In the closed position, a key 150(2) can operate locking device 140(3) so that locking tab 145(3) engages base member 110(2). Thus, when center panel 120(2) in the closed position to hold side panels 130(3) and 130(4) in place, locking tab 145(3) engages base member 110(2) and key 150(2) is removed, system 100(2) is in a closed and relatively tamper-resistant configuration, with printed media visible through each of windows 180(4)-180(6).

FIG. 12 shows an exploded view of a media display system 100(3) that is attachable to a restraint bar that lowers in front of a ski-lift chair (not shown). FIG. 12 may not be drawn to scale. Like systems 100(1) and 100(2) (FIG. 1, FIG. 11), system 100(3) may display printed media.

System 100(3) includes a base member 110(3) and a top panel 128(1) shown disengaged from base member 110(3). Base member 110(3) forms a flange 118 about a bottom surface of base member 110(3), and forms ribs 116(1), 116(2) that, along with top panel 128(1), hold printed media 200(1)-200(3) in place within system 100(3) so as to be visible through windows 180(7)-180(9), as shown. Each of windows 180(7)-180(9) may include a transparent material such as glass or clear plastic to protect printed media 200(1)-200(3), or windows 180(7)-180(9) may simply be openings in top panel 128(1). Top panel 128(1) connects to base member 110(3) by a groove 172(1) engaging with flange 118 along one edge, and connectors 210 fastening another edge. Lines 211 indicate the points of top panel 128(1) and base member 110(3) that connect via connectors 210. Connectors 210 may be of a type that brings top panel 128(1) into close contact with base member 110(3) when fully tightened, but only partially releases top panel 128(1) when loosened (e.g., each such connector 210 may continue to engage top panel 128(1) but allow top panel 128(1) limited movement with respect to base member 110(3) when loosened). Top panel 128(1) forms slots 220(1)-220(3) that facilitate installation and/or exchange of printed media 200(1)-200(3) as explained further below. A dashed line F7 indicates a location shown in cross section in FIG. 14A and FIG. 14B. In FIG. 12, a frontward (F) and rearward (R) direction are indicated by a short, dashed arrow, and an upward (U) and downward (D) direction are indicated by a longer dashed arrow that is approximately parallel to lines 211.

FIG. 13 shows a rear edge detail of system 100(3). Top panel 128(1) forms a groove 172(1) that extends about an edge of top panel 128(1) that is opposite an edge that attaches via connectors 210. (Although FIG. 12 shows groove 172(1) in a forward, swept edge and slots 220(1)-220(3) and connectors 210 in a rear, straight edge of top panel 128(1), it is appreciated that groove 172(1) may alternatively be in the rear edge, and slots 220(1)-220(3) and connectors 210 in the front edge.) Flange 118 engages groove 172(1), as shown, such that top panel 128(1) fastens to base member 110(3) along the length of an edge so engaged, so as to hold top member 128(1) to base member 110(3) if another edge is engaged (e.g., by connectors 210).

One method of installing printed media 200(1)-200(3) into system 100(3) includes removing top panel 128(1) completely (for example, as shown in FIG. 12), placing the printed media onto base member 100(3), manipulating top panel 128(1) to engage groove 172(1) with flange 118, then fastening connectors 210.

A second method of installing printed media 200(1)-200(3) into system 100(3) is illustrated in FIGS. 14A and 7B. FIG. 14A is one alternate view showing a partial cross-section along line F7 shown in FIG. 12. In FIG. 14A, a connector 210 (not in plane F7, thus shown in dashed lines) holds top panel 128(1) in place so that top panel 128(1) seats against base member 110(3), holding printed media 200(2) in place. FIG. 14B is another alternate view showing a partial cross-section along line F7 shown in FIG. 12. In FIG. 14B, connector 210 is loosened such that top panel 128(1) remains fastened to base member 110(3), but can move so as to open a channel 230 that permits access to printed media 200(2), permitting removal or replacement of media 200(2).

FIG. 15 shows a media display system 100(4) that is attachable to a restraint bar that lowers in front of a ski-lift chair (not shown). FIG. 15 may not be drawn to scale. Like systems 100(1) and 100(2) (FIG. 8 and FIG. 11), system 100(4) may display printed media, and is configured for keyed access, as explained immediately hereafter.

System 100(4) includes a base member 110(4) and a top panel 128(2) that connects to base member 110(4) via hinges 190(2)-190(4). Although three hinges 190(2)-190(4) are shown, it is appreciated that any number or style of hinges are within the scope of the present disclosure. FIG. 15 shows top panel 128(2) in an open position. Top panel 128(2) includes windows 180(10)-180(12), as shown; each of windows 180(10)-180(12) may include a transparent material such as glass or clear plastic, or windows 180(10)-180(12) may simply be openings in top panel 128(2). Base member 110(4) forms ribs 116(3), 116(4) that, along with top panel 128(2), hold printed media (not shown in FIG. 15) in place within system 100(4) so as to be visible through windows 180(10)-180(12), as shown.

Installation of printed media into system 100(4) may begin with top panel 128(2) in the open position. Printed media may be placed on base member 110(4), or affixed to an underside of top panel 128(2). Once printed media are in place, top panel 128(2) may swing down into a closed position, so that keys 150(3) and 150(4) may lock locking devices 140(4) and 140(5) respectively to base member 110(4), locking top panel 128(2) in the closed position, with printed media visible through windows 180(10)-180(12). It is appreciated that a single key (e.g., either of keys 150(3) and 150(4)) may operate both of locking devices 140(4) and 140(5).

FIG. 16 is a detail view of a hinge 190(5) that may be used, for example, as one or more of hinges 190(2)-190(4), FIG. 15. Base member 110(4) forms an extension 196 that includes an axle 194. Top panel 128(2) forms flanges 192(1) and 192(2) that may snap into place about axle 194.

FIG. 17 shows a media display system 100(5) that is attachable to a restraint bar that lowers in front of a ski-lift chair (not shown). FIG. 17 may not be drawn to scale. System 100(5) includes a base member 110(5) and a transparent top panel 128(3) that are held together with clips 212 (only some of clips 212 are numbered in FIG. 17, for clarity of illustration). Base member 110(5) may be formed, for example, of structural foam and top panel 128(3) may be formed of a clear plastic such as Plexiglas that is vacuum formed to the shape of base member 110(5). Printed media 200(4) is held between base member 110(5) and top panel 128(3), and are visible through top panel 128(3). Although printed media 200(4) is shown as a single article in system 100(5), it is appreciated that printed media can be of any number and shape.

FIG. 18 is a detail view showing one clip 212 holding together top cover 128(3), printed media 200(4) and base member 110(5). Clip 212 may be formed, for example, of spring steel. Top cover 128(3) may form a flange 129 that clip 212 snaps over, in order to hold clip 212 in place (although it is appreciated that not only top cover 128(3) but also base member 110(5) or both may have flanges like flange 129 to hold clip 212 in place).

FIG. 19 illustrates a media display system 100 (e.g., any of media display systems 100(1)-100(5)) installed on a ski-lift chair 300. Chair 300 is suspended from cable 310, and has a restraint bar 320 shown in a “down” position. In FIG. 19, a frontward (F) and rearward (R) direction are indicated by a short, dashed arrow, and an upward (U) and downward (D) direction are indicated by a longer dashed arrow that is approximately parallel to a pole 330 that suspends chair 300. Restraint bar 320 may also assume an “up” position by rotating it in the direction of arrow 350 about one or more pivots 340. A rider of chair 300 typically boards the chair with restraint bar 320 in the “up” position, and once chair 300 lifts the rider off the ground, the rider pulls restraint bar 320 into the “down” position shown. It is appreciated that chair 300 and restraint bar 320 may take differing forms, or mount with one another differently, as compared to the configuration shown in FIG. 19 without departing from the scope hereof.

FIG. 20 shows a portion of a media display system 400 for a ski-lift chair. System 400 includes a base member 402 and a frame 405 that connects to base member 402 via three hinge hooks 404 (only portions of base member 402 and frame 405 are shown in FIG. 20). Although three hinge hooks 404 are shown in the partial view of FIG. 20, it is appreciated that any number or style of hinge hooks may be utilized. FIG. 20 shows frame 405 in an open position. Frame 405 may be, for example, a center frame or a side frame of system 400. A region noted as A is shown in greater detail below in FIG. 21 and FIG. 22; other features of system 400 are shown in FIG. 23 and FIG. 24.

FIG. 21 is an enlarged view of region A shown in FIG. 20. FIG. 21 shows hinge hook 404 attached to frame 405 with a screw 406. Alternatively, rivets or other mechanical fasteners may be utilized to attach hinge hook 404 to frame 405.

FIG. 22 is a rear view of region A of FIG. 20 where base member 402 connects to frame 405 via hinge hook 404, but with frame 405 in a closed position over base member 402.

FIG. 23 shows a locking mechanism 410 positioned on an underside of base member 402. Although FIG. 23 shows locking mechanism 410 integrated with base member 402, it is appreciated that locking mechanism 407 may also be positioned in frames of a media display system (e.g., frame 405). Locking mechanism 410 includes a lock 407 and a latch 409, and is operated by a key 408. Printed media (e.g., printed media 60, 62, 64 or 200) may be affixed to an underside of frame 405 or placed on base member 402 such that when frame 405 swings down into a closed position (as shown, for example, in FIG. 24) frame 405 holds the printed media in place.

The changes described above, and others, may be made in the media display systems for ski-lift chairs described herein without departing from the scope hereof. For example, each of base members 22 or 110 or 402, center panels 50 or 120, side panels 52, 54 or 130, top covers 128 and frame 405 may be formed of a wide variety of materials such as plastic, metal, hard rubber, epoxies, fiberglass, and/or combinations thereof. Indicia may be embossed, etched, or molded into any of base members 22 or 110, center panels 50 or 120, side panels 52, 54 or 130, top covers 128, and frame 405. Tabs 58, hinges 190, hooks 127, hinge hook 404, locking mechanisms 140 or 410, locking tabs 145 are not limited to the exact form and/or placement shown; in particular, it is appreciated that illustrated arrangements of hinges and fasteners may be reversed front-to-rear or side-to-side. Locking devices in base members, that engage panels or covers, may be substituted for locking devices in such panels or covers that engage a base member. Locking devices may be operated by tools other than keys. Media display systems for ski-lift chairs may include flanges or overhangs in addition to those shown, to increase weather resistance or tamper resistance of such systems. Windows 180 may be formed of glass or plastic, or may be omitted entirely. Printed media 60, 62, 64 or 200 may be printed on paper or plastic or combinations thereof, such as plastic laminated about paper. Media display systems for ski-lift chairs are not limited to the illustrated configurations of center and side panels but may include different numbers and arrangements of panels.

It should thus be noted that the matter contained in the above description or shown in the accompanying drawings should be interpreted as illustrative and not in a limiting sense. The following claims are intended to cover all generic and specific features described herein, as well as all statements of the scope of the present method and system, which, as a matter of language, might be said to fall there between.
